## 문제

A 5-year-old child with acute post-streptococcal glomerulonephritis is admitted to the pediatric unit. The child presents with periorbital edema, hypertension (BP 140/90 mmHg), and oliguria. Laboratory results show proteinuria and hematuria. Which nursing intervention should be the priority?

## 보기

1. Encourage increased fluid intake to promote kidney function
2. Monitor blood pressure every 2 hours and implement seizure precautions **✔ 정답**
3. Administer diuretics immediately to reduce edema
4. Restrict all physical activity and maintain strict bed rest

**정답: 2**

## 해설

Priority is monitoring BP every 2 hours and seizure precautions to prevent hypertensive encephalopathy, the most dangerous complication. Other interventions are contraindicated or lower priority.

Clinical Context and Pathophysiology

This child is presenting with classic manifestations of acute post-streptococcal glomerulonephritis (APSGN), an immune-complex mediated inflammation of the glomeruli following a group A beta-hemolytic streptococcal infection. The deposition of antigen-antibody complexes triggers complement activation and glomerular injury, leading to a reduced glomerular filtration rate (GFR). The clinical triad of periorbital edema (fluid retention), hypertension (volume overload and renin-angiotensin-aldosterone system activation), and oliguria with hematuria/proteinuria directly reflects this underlying pathology. APSGN is a common cause of acute nephritic syndrome in children, and while most recover, it can lead to serious complications if not managed promptly [2]. The priority in acute management is recognizing and mitigating life-threatening complications, particularly those arising from severe hypertension and fluid-electrolyte imbalance.

Analysis of Nursing Interventions

The question asks for the *priority* nursing intervention, which must be determined using an ABC (Airway, Breathing, Circulation) and safety-first framework. Let's analyze each option in the context of the child's presentation with a blood pressure of 140/90 mmHg.

Option 1: Encourage increased fluid intake to promote kidney function.

This is contraindicated. The child is in a state of volume overload with oliguria and edema due to a compromised GFR. Increasing fluid intake would worsen fluid retention, exacerbating hypertension, edema, and the risk of pulmonary edema—a rare but life-threatening complication of APSGN [3]. Management focuses on fluid *restriction*, not promotion.

Option 2: Monitor blood pressure every 2 hours and implement seizure precautions.

This is the priority. The child's blood pressure of 140/90 mmHg represents significant hypertension for a 5-year-old and is a direct consequence of volume overload and impaired renal function. The most immediate and serious risk of severe hypertension is hypertensive encephalopathy, which can manifest as seizures. This neurological complication is a medical emergency. Frequent blood pressure monitoring allows for early detection of worsening hypertension, and seizure precautions (padding side rails, ensuring suction and oxygen are at the bedside) are a critical safety measure to prevent injury. This intervention directly addresses the most imminent threat to the child's neurological and circulatory status.

Option 3: Administer diuretics immediately to reduce edema.

While diuretic administration is a key component of medical management for APSGN to manage volume overload and hypertension, it is a physician-initiated intervention. The priority *nursing* action is not to independently administer a medication but to perform a critical assessment and implement safety measures based on that assessment. The nurse would monitor for the diuretic's effectiveness and side effects after a provider's order is received.

Option 4: Restrict all physical activity and maintain strict bed rest.

Activity restriction is not a priority intervention in the acute phase. While a quiet environment is beneficial for managing hypertension, it does not take precedence over direct monitoring for and prevention of life-threatening neurological complications. Strict bed rest is not a standard, evidence-based recommendation for APSGN and does not address the primary pathophysiological threat.

Clinical Reasoning and Priority Setting

The priority is grounded in the pathophysiology of severe hypertension in the setting of acute nephritis. Volume overload and vasoconstriction increase systemic vascular resistance, which can overwhelm cerebral autoregulation, leading to cerebral edema and seizures. A case report of a pediatric patient with PSGN highlights how rapidly the condition can progress to critical states, including acute pulmonary edema and critical hyperkalemia, underscoring the need for vigilant monitoring for complications [3]. While hematuria and proteinuria are diagnostic hallmarks of APSGN , they do not pose an immediate threat to life. The nursing priority is to first address the hypertensive crisis risk, which is best accomplished by frequent monitoring and implementing safety precautions to prevent secondary injury from a potential seizure.

## 임상 시나리오

Managing Hypertensive Crisis in Pediatric APSGNPrioritizing Safety and Neurological Protection
In a child with acute post-streptococcal glomerulonephritis and a BP of 140/90 mmHg, the immediate risk is hypertensive encephalopathy. This can manifest as severe headache, vomiting, vision changes, and generalized seizures. The priority nursing action is frequent neurological assessments and implementing seizure precautions.

Obtain accurate blood pressure readings every 1-2 hours using an appropriately sized cuff. Anticipate the administration of antihypertensives (e.g., hydralazine, labetalol) as prescribed. The goal is to lower BP gradually to prevent cerebral ischemia, not to normalize it immediately.

CautionDo not encourage increased fluid intake; the child is in a state of volume overload. Strict fluid restriction and daily weight monitoring are essential. Diuretic therapy requires a specific order and is not the first independent nursing action.

## 핵심 개념

- **Acute Post-Streptococcal Glomerulonephritis (APSGN)** — Immune-complex mediated inflammation of the glomeruli following a group A beta-hemolytic streptococcal infection, leading to decreased GFR, fluid retention, hypertension, and hematuria.
- **Hypertensive Crisis in APSGN** — Severe hypertension resulting from volume overload and RAAS activation that can lead to hypertensive encephalopathy, seizures, and cerebral ischemia, requiring immediate monitoring and safety measures.
- **Seizure Precautions** — Safety interventions including padded side rails, suction equipment at bedside, and ensuring IV access to protect a patient at high risk for seizure activity from injury.
- **Oliguria** — Reduced urine output, often defined as less than 1 mL/kg/hr in children, indicating significant impairment of glomerular filtration rate.
